摘 要Zigbee是一种近距离、低复杂度、低功耗、低速率、低成本的双向无线通讯技术。主要用于短距、低速且低功耗的数据传输和典型周期性、间歇性和低反应时间的数据传输应用。

本控制系统采取了集散式控制结构，每个节点拥有一个CC2530控制器，单独对区域内所有设备进行控制，同时以协调器为主节点，通过Zigbee网络对所有分散的终端节点进行统一控制和调度。

整个园圃控制系统可分为硬件部分和软件部分。硬件主要包括浇灌设备、传感器设备、计算机控制设备和监控设备；软件部分主要包括Zigbee终端程序、Zigbee协调器程序、PC上位机监控程序。其中Zigbee协调器程序和PC上位机监控程序是整个控制系统的核心。85051

本系统实现环境温湿度采集，土壤湿度采集，并根据预置的灌溉策略实现自动灌溉。同时实现ZigBee物联网与PC机的无线通讯，并实现PC上位机对ZigBee终端的信息监控，灌溉调节功能。

ABSTRACT Zigbee is a close-up bi-directional wireless communication technology with many superior features such as low complexity, low power consumption, low-rate and low cost。 ZigBee is mainly used in short-range, low velocity, low power data transmission and typically used in short reaction time and typical cyclical/intermittent applications。

This control system has centrally-distributed control architecture and each node has a CC2530 controller to operate all the devices in certain area separately。 At the same time, the coordinator as the central node to control and dispatch all distributed terminal nodes uniformly by Zigbee network。

The whole garden control system includes hardware and software。 The hardware mainly includes irrigation equipment, sensor equipment, computer control equipment and monitoring equipment; the software mainly includes the Zigbee terminal program, the Zigbee coordinator program, and the PC host computer monitoring program。 And the Zigbee coordinator program and the PC host computer monitor program are the core of the whole control system。

The system can collect soil moisture and air temperature and humidity。 According to preset irrigation strategy, it can realize automatic irrigation。 Meanwhile the system can realize the function of wireless communication between Zigbee and PC, adjustment of irrigation strategy and information monitoring from PC to Zigbee terminal。

Key words: ZigBee; CC2530; Temperature and humidity measurement; Garden irrigation; PC
